iio: st_pressure: Fix data sign
Datasheet of each device (lps331ap, lps25h, lps001wp, lps22hb) says that the pressure and temperature data is a 2's complement. I'm sending this the slow way, as negative pressures on these are pretty unusual and the nature of the fixing of multiple device introduction patches will make it hard to apply to older kernels - Jonathan.
